102. STM32CubeIDE Servo Motor. PWM with STM32F446RE Nucleo

Control from 0 degree to 180 degree
50 Hz PWM signal for SG 90

As I normally do with STM32F103C8T6, I have just changed the HCLK Frequency to 180MHz assuming that HSE auto-select. Later I found that we have to manually tick the HSE button for Nucleo STM32F446RE. No worries. It will still work fine without HSE

Nizar thanks for the video. On the SG90 data sheet I notice that the duty cycle is in a range of 1-2ms, so I was wondering why you have set the range to 0.5 to 2.5ms?
